The Singer's Mask from Hal Leonard was designed and manufactured by Broadway professionals to directly address the needs of professional singers. This face mask helps contain droplets while also allowing space around the mouth to sing comfortably. A non-woven polyesther is sandwiched between layers of cotton muslin with two small windows on each side to aid air flow. The top edge of the Singer's Mask has a flexible wire inside for a comfortable, custom fit. This reusable face mask is washable in cold water.
